    Inverse of a square matrix in C

    thanks alot..! i'll try this in microC software which involves some special commands for matrices and let you know if there is a problem.:blushing:

    Inverse of a square matrix in C

    Thanks for the reply. The algorithm is pretty tough and confusing enough to break heads. The matrices are dynamic type,3by3 and symmetric.Thanks for the link.:blushing:

    Inverse of a square matrix in C

    Hello all. Iam trying to implement an algorithm which involves several matrix inversions.The algorithm is an extended kalman filter which is a recursive one. Can anybody help me in writing a C program to solve the inversion problem or any good links? thanks in advance..!

    Programming PICs in C

    Hi all. Iam trying to write extended kalman filter algorithm in microC (dspic) software. My question is how to invert a matrix in that software? I have read the manual but could'nt find any command for matrix inversion.pls check out the attachment. can anyone help me out...! thanks in advance.

    Help, very simple mikroC compiler question.

    hello..you can find the hex file in the same directory in which you have created the project. microC generates hex file only if it is built without any errors. waiting to hear from you..!

    Gyroscope for angular rotation

    Here is some information regarding the equation:[PLAIN]www.egr.msu.edu/classes/ece480/goodman/.../Final%20Report_Web.doc[/URL] ON PAGE NUMBER 31. Other documentation:From IEEE paper(Application of an Inertial Navigation System to the Quad-rotor UAV using MEMS Sensors Tin Thet Nwe, Than Htike...

    Gyroscope for angular rotation

    hello thanks for the reply. Iam giving 3Volts as the supply for the gyro. Should i use (Vout-Voffset)*5/1024/sensitivity or (Vout-Voffset)*3/1024/sensitivity Right now iam using the 1st equation.On stationary the gyro outputs around:x-axis -7.28deg/s and z axis -7.28deg/s when i rotate quite...

    Gyroscope for angular rotation

    Hey i got the correct answers.no need to invert the factor 5000/1024. The correct equation is: x_deg/sec=(Vout-Voffset)*(5/1024)/0.00067(V/deg/s) 0.00067--->sensitivity Voffset--->1.23V as per datasheet. On stationary, the gyro outputs near 7deg/sec(due to erros) On rotating rapidly along...

    Gyroscope for angular rotation

    The datasheet reads: 1.23V+SoA*1500=2.23V for 1500deg/s Where, 1.23 is the Vref or Voffset SoA=0.67mV/deg/s That means Vref+SoA*angle=Vout implies-->angle=(Vout-Vref)/SoA From IEEE paper(Application of an Inertial Navigation System to the Quad-rotor UAV using MEMS Sensors Tin Thet Nwe...

    Gyroscope for angular rotation

    OH sorry..! It's in the 9th page figure4 below the diagram.:-) He has given the equations for the full scale deflection i.e,1500 deg/s.

    I didn't understand what you are saying.Can you be more elaborative please?

    Gyroscope for angular rotation

    BUT, as per the datasheet the equations are correct it seems.Here is the link for data sheet:http://www.sparkfun.com/products/9412 Full scale reading:1500°/s max deflection is a lot! This means you've really got to spin the board quickly to see a change in output. This sensor range is good...
